摘要： Highly dense shaped parts are produced with a powder metallurgic process. The parts are formed of an alloy that, besides of at least 20 weight % chromium, consists of iron and one or several additional alloy portions that in sum do not amount to more than 10 weight %. The part is produced by pressing and sintering to near final shape a ready-to-press powder where the additional alloy portions are introduced in form of a master-alloy powder. The master-alloy may contain the following variations: the additional alloy portions and the iron portions; or the additional alloy portions, the iron parts, and the chromium portions; or additional alloy portions and the chromium portions.

摘要： A molding is produced with a disk-shaped or plate-shaped basic body having a large number of knob-like and/or web-like elevations which merge into the basic body with inclined side surfaces. The molding is produced by pressing and sintering powdery raw materials close to the final shape. First, the boundary surfaces of the basic body are pressed to final shape as far as the transition regions of the elevations and the elevations are pressed to an oversize. The projection height of the elevations from the basic body is greater than the projection height in the finally pressed state. Their side surfaces form an angle of inclination in the range from 90°-150° with the respectively adjacent boundary surface of the basic body. Then the elevations are pressed to near final shape while the angle of inclination is enlarged to a greater value.

摘要： The invention relates to a process for producing a molding, comprising a disk-like or plate-like basic body —5— having a large number of knob-like and/or web-like elevations —4—3— which merge into the basic body —5— with inclined side surfaces, by means of pressing and sintering powdery raw materials close to the final shape. According to the invention, the pressing is carried out in a two-stage pressing operation. In the first stage the boundary surfaces of the basic body —5— are pressed to at least the approximate final shape as far as the transition regions of the elevations —3—4— and, at the same time, the elevations —3—4— are pressed to an oversize. The projection h′ of the elevations —3—4— from the basic body —5— is greater by 10%-150% as compared with the projection h from the basic body —5— in the finally pressed state. Their side surfaces form an angle of inclination α′ in the range from 90°-150° with the respectively adjacent boundary surface of the basic body —5—. In the second stage, the elevations —3—4— are pressed to at least approximately the final shape, the angle of inclination α′ being enlarged to a value α which lies in the range from 95°-170°.

摘要： A shaped part that is particularly suited as an interconnector or an end plate for a fuel cell stack, is produced by pressing and sintering a pulverulent starting material. The shaped part has a disc-shaped or plate-shaped basic body with a multiplicity of knob-like and/or ridge-like elevations with a height h. In cross section, each elevation has two inclined side flanks which lead, proceeding from an end contour of the elevation, via rounded corner portions, with a radius r or r′ directly or via intermediate rectilinear portions, into curved portions, with a radius R or R′, which in turn merge into the surface contour, of the basic body. The rectilinear portions, or, in the case of a direct transition of the rounded corner portions, into the curved portions, the tangents at the point of the transition, have an angle of inclination α or α′ with respect to the surface contour, in the range of 95° to 135°. The radius R or R′ is in the range of 0.15 to 1 mm and the height h is dimensioned such that the ratio R:h or R′:h is in a range of 0.25 to 1.
